Solar lawn lights require a light-controlled switch, and designers often use photoresistors to automatically switch the lights on and off.

The application of photosensitive sensors in solar lawn lights is mainly to achieve automatic control of light switching. This sensor can sense the intensity of ambient light and transmit signals to the control system, so that the light is automatically turned on when the light is dim and automatically turned off when the light is sufficient. This design not only improves energy efficiency, but also enhances the convenience of use.

Solar lawn lightsare usually equipped with the following sensors to improve their intelligence and energy efficiency:

1. Photosensitive sensor (light control sensor)

Function: Detect the intensity of ambient light and automatically control the switch of the light.

Application: Automatically turn on when it is dark and automatically turn off when it is light.

2. Infrared sensor (motion sensor)

Function: Detect the movement of human or animals.

Application: Automatically turn on the light when a person or animal approaches, and automatically turn off after a period of time, saving energy and enhancing safety.

3. Microwave sensor

Function: Detect moving objects through microwaves, with high sensitivity and wide coverage.

Application: Suitable for scenes that require a larger detection range, such as large lawns or gardens.

4. Temperature sensor

Function: Monitor ambient temperature.

Application: Adjust the working state of lamps in extreme temperatures to prevent damage from overheating or overcooling.

5. Humidity sensor

Function: Detect ambient humidity.

Application: Adjust the working state of lamps in humid environments to prevent damage to circuits caused by moisture.

6. Time control sensor

Function: Control the switch of lights according to preset time.

Application: Users can set specific time periods to turn on or off lamps.

7. Light intensity adjustment sensor

Function: Adjust the brightness of lights according to ambient light intensity.

Application: Increase brightness when light is dim and reduce brightness when light is bright, saving energy and extending battery life.

Summary:

Common sensors for solar lawn lights include photosensors, infrared sensors, microwave sensors, temperature sensors, humidity sensors, time control sensors, and light intensity adjustment sensors. These sensors improve the intelligence, energy saving, and safety of lamps, and users can choose suitable products according to their needs.
